A new model for the relations between longitudinal personality profiles and psychological functioning through middle age
2014
Personality traits and psychological functioning were assessed three times between the ages from 33 to 50 years (average N = 250) in the Finnish Jyvaskyla Longitudinal Study of Personality and Social Development. Five longitudinal personality profiles were extracted: Resilient, Overcontrolled, Undercontrolled, Reserved, and Ordinary. The Resilients (neuroticism low, other traits high) were higher in optimism and personal control over development than the Overcontrolleds (neuroticism high, other traits low) at all ages, whereas the Overcontrolleds were higher in anxiety and depressive symptoms. Other profiles were between them in these characteristics. The Undercontrolleds (high openness and…
A Mathematical Approach to the Body-Mind Problem from a System Personality Theory (A Systems Approach to the Body-Mind Problem)
2013
The dynamics of both the General Factor of Personality and the personality biological indicators, as a consequence of a stimulus, can be described with a short-term dynamic model (the response model). The invariance of the response model at both levels of description (psychological and biological) leads to deduce the bridge model with which psychological and biological levels of description can be related. The bridge model is the key tool to deal with the body–mind problem. An application case is presented setting up an experimental design with two subjects. The General Factor of Personality, c-fos and glutamate dynamics are evaluated as a consequence of a methylphenidate dose intake. The r…
Extraversion and Neuroticism as antecedents of emotion regulation and dysregulation in adulthood
2001
This longitudinal study examined the role of Extraversion and Neuroticism as antecedents of emotion regulation and dysregulation among 89 women and 81 men. When participants were 27 years old, their Extraversion and Neuroticism were assessed with the standardized version of the Eysenck Personality Questionnaire. At age 33, they completed the Big‐Five Personality Inventory, an authorized adaptation of the NEO Personality Inventory. Emotion regulation, operationalized as an active attempt to turn a negative emotion toward a more positive direction, and measured by the Repair subscale of the Meta‐Regulation Scale, and emotional social support, as measured by the Life Situation Questionnaire, …
Changing the General Factor of Personality and the c-fos Gene Expression with Methylphenidate and Self-Regulation Therapy
2012
[EN] A deepening in the biological nature of the general factor of personality (GFP) is suggested: the activation level of the stress system is here represented by the gene expression of c-fos. The results of a single case experimental design are reported. A model of four coupled differential equations that explains the human personality dynamics as a consequence of a single stimulant drug intake has been fitted to psychological and biological experimental data. The stimulant-drug conditioning and its adaptation to the considered mathematical model is also studied for both kinds of measures. The dynamics of the cfos expression presents a similar pattern to the dynamics of the psychological …
MCM-41-CdS nanoparticle composite material: Preparation and characterization
2010
The preparation and characterization of a hierarchical material constituted by a mesoporous silica MCM-41 whose mesochannels contain CdS nanoparticles capped with both bis(2-ethylhexyl) amine and bis(2-ethylhexyl) sodium sulfosuccinate is reported. MCM-41 powder was synthesized by using the LCT methodology. CdS nanoparticles were obtained within the inversed micelle core of a water/ AOT/n-heptane microemulsion. Nanoparticles growth was followed by means of UV–Vis spectroscopy and was inhibited by BEA addition. The CdS-capped nanoparticles were separated by centrifugation, washed with water and ethanol and finally dispersed in n-heptane. The insertion of CdS nanoparticles into MCM-41 mesocha…
Rapid One-Step Fabrication of Graphene Oxide-Decorated Polycaprolactone Three-Dimensional Templates for Water Treatment
2020
Coating of flexible substrates is crucial to prepare versatile, multifunctional materials. However, exploration of effective fabrication approaches is still a challenging issue, because the pathways generally proposed require time-consuming, multistep protocols. Here, we developed a one-pot process for decorating either pearl necklace-like or fibrous fluffy-like structures of polycaprolactone (PCL) with graphene oxide (GO) skin. PCL solutions were dry jet-wet electrosprayed or electrospun into a stirred liquid collector constituted by ethanol-containing GO nanoparticles. The stirred liquid collector enables the formation of 3D-structures, whose microarchitecture can be designed by controlli…
Advances in the general factor of personality dynamics
2018
This paper presents a dynamical integro-differential equation to reproduce the dynamical response of the General Factor of Personality (GFP) to a stimulus dose, particularly to a stimulant drug dose. The model is called in the past authors publications as response model. We refer to it as the old response model, due to a new response model presented here that solves partially the problem of the model validation: how to forecast the GFP dynamical response from a previous model calibration. The application case presented is an individual ABC experimental design where the stimulus used is methylphenidate.
The general factor of personality: History of an interdisciplinary venture
2018
The General Factor of Personality (GFP) is a new psychological approach of the study of the human personality that is based on the idea that, as in the case of General Intelligence, there is a personality super-factor that agglutinates and represents all the other aspects of personality. Therefore, it can be considered as a system of personality subsystems, or a global and integrated system of all the different components from the personality. Thus, the GFP also can be studied from Psychology and from General Systems Theory. As far as psychology, the theoretical and empirical boarding of the GFP has been limited the structural study, that is to say, to the correlational and structural study…
Multilevel Latent Profile Analysis With Covariates : Identifying Job Characteristics Profiles in Hierarchical Data as an Example
2018
Latent profile analysis (LPA) is a person-centered method commonly used in organizational research to identify homogeneous subpopulations of employees within a heterogeneous population. However, in the case of nested data structures, such as employees nested in work departments, multilevel techniques are needed. Multilevel LPA (MLPA) enables adequate modeling of subpopulations in hierarchical data sets. MLPA enables investigation of variability in the proportions of Level 1 profiles across Level 2 units, and of Level 2 latent classes based on the proportions of Level 1 latent profiles and Level 1 ratings, and the extent to which covariates drawn from the different hierarchical levels of th…
